1 Claim.

The invention relates to cutter boxes or dispensing cartons for containing rolls of paper and the like, such for instance as rolls of waxed paper to be withdrawn in desired lengths and then tom ofi along the cutter edge of the box, an. object of the invention being to provide a box of this description adapted to be made with a considerable saving in the paper stock used and at a reduced cost. Another object is to provide an improved cover for the box which isformed of a one-piece blank, said cover embodying certain interlocking features. Other objects and advantages will appear hereinafter.

The invention consists in the novel construction and combinations of parts as hereinafter set forth in the claim.

In the accompanying drawing,

Figure 1 is a perspective view of the invention with cover open, and one end portion of cover unfolded.

Figure 2 is an end view of the box, with cover closed.

Figure 3 is a plan view of the blank.

In the drawing, the numeral l designates the open-top carton, closed by a cover 2 and adapted to be formed from a one-piece blank, said blank having portions adapted to form the bottom, front, back and end walls and the cover of the carton. The top of the cover is provided with a forward depending extension 3, connected thereto along a fold line and lapping over the upper part of said front wall, said forward extension having at each end thereof a triangular extension}, connected thereto along a fold line and providing depending cover end portions lapping over upper parts of said end walls, said triangular extensions having each a rectangular flap 5 integrally connected thereto along a, fold line which forms a continuation of the first named fold line when the flap is in unfolded position, said flap being nearly the width of and folded into a position adjacent the inner surface of said cover top. The outer free edge portion of each rectangular flap is provided with a notch 1, forming a corner tongue 8. and said cover top has adjacent its inner longitudinal edge angular slits 8 forming angular tongues 6' cooperating with the corner tongues of said flaps when the latter are in folded position to lock the flaps in 1939, Serial No. 259,681

such position. The engagement of the corner tongues B with the angular slits 6 and tongues t is held by inherent elasticity of the paper, that is to say the tendency of the flaps 5 to move outwardly on the fold lines 9 as a center results in more secure engagement of said tongues in said slots.

The open-top carton is formed in well known manner, the bottom l0 having end flaps l0, the front ll having end flaps l I, provided each with a slot II", the back l2 having end flaps l2 provided each with a hooked tongue 12" engaging the related slot H" to form the box ends, the flaps ill of said bottom being located within flaps II and I2 of the box ends.

In the blank before folding, all of the flaps I0, II' and I2 extend outwardly to approximately the same extent, and as the end extensions 4 and the flaps 5 also extend outwardly to approximately the same extent as the flaps In, H and I2, the box is capable of being made of a rectangular sheet of paper stock with minimum waste.

I claim:

A carton having an open top closed by a cover and formed from a one-piece blank having portions forming the bottom, front, back and end walls and the cover of the carton, the top of said cover having a forward depending extension connected thereto along a fold line and lapping over the upper part of said front wall, said forward extension having at each end thereof a triangular extension connected thereto along a fold line and having a rectangular flap, said ilap being integrally connected with said triangular extension along a fold line which forms a continuation of the first named fold line when the flap is in unfolded position, said flap being nearly the width and folded into a position adjacent the inner surface of said cover top, the outer free edge portion of each rectangular flap having a notch therein providing a corner tongue, and said cover top having adjacent its inner longitudinal edge angular slits forming angular tongues cooperating with the corner tongues of the flaps when the latter are in folded position to lock the flaps in such position,
